WASHING-MACHINE.

SPECIFICATION formingpart of Letters Patent No. 607,913, dated July 26, 1898.

Application filed March 8, 1898.

To aZZ whom it may concern;

Be it known that I, JOHN R. CARTER, of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in WVashing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in washing-machines, and more particularly to that class of machines comprising a tub, an oscillating lower rubber, and an oscillating upper rubber, the latter being carried by the cover of the machine and the two rubbers being actuated to move in opposite directions by a crank-shaft.

Myinvention consists in the parts and combinations of parts, as will be more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in vertical longitudinal section of a washing-machine embodying my invention. Fig. 2 is a transverse vertical sectional View of same. Fig. 3 is a detached view of the slotted rocking arm. Fig. 4 is a View of the actuating-arm for the upper rubber. Fig. 6

' is a view in longitudinal vertical section of a modified form, and Figs. 5, 7, and 8 are details.

A represents the tub, approximately semicylindricallongitudinally and provided with a cover B, hinged at one end to the tub.

Located within the tub is the rubber 0, approximately semicylindrical in form and provided on its upper face with ribs a in the usual manner. This rubber O is designed to hold the clothes to be washed and is provided centrally at or near the upper edges of its sides with trunnions or pivots b, which latter rest in bearings in the tub A. This rubber O is supported or suspended 011 these trunnions or pivots, and hence is free to swing or oscillate within the tub. Attached to one end of the oscillating rubber O is the pitman D. This pitman is made in two sections 1) Z),

the lower one,b,being pivotally attached to the rubber 0, while the upper section b is mounted on the crank c of the operating-shaft E. One section of this pitman is provided witha socketb for the reception of the adjacent end Serial No. 673,094.. (No model.)

of the other section, and the meeting ends of the two sections are secured together by a setscrew or other device b By disconnecting the two sections of this pitman the cover can be turned clear over without meeting any resistance from the lower rubber and leaves the rubber free to be removed-from the tub.

The operating-shaft E is mounted in suitable bearings on the cover B and is provided at one end, at one side of the cover, with a liy-wheel and handle for actuating the rubbers and at its opposite end, approximately over the longitudinal center of the cover, with the crank c. Mounted on the crank 0 alongside of the pitman D is one end of the pitman F, the other end of said pitman F being pivotally connected to the upper end of the slotted rocking arm G, the lower end of which is pivotally mounted in a bearing carried by the cover. From this it will be seen that as the shaft E is rotated the rubber O and arm G are rocked on their respective bearings.

H is the upper rubber, having a lower face approximately conforming in shape to the shape of the upper face of the lower rubber and provided with ribs in the usual manner. The rubber H is provided centrally at its upper side edges with trunnions e, which rest and move in the elongated slotted bearings e, secured to the inner faces of the sides of the cover.

When there are no clothes in the washer, the trunnions 6 rest on the lower walls of the slot; but as clothes are deposited on the lower rubber the upper rubber yields or rises vertically, and while its weight is then sustained by the clothes the trunnions sustain it from lateral or longitudinal displacement.

Secured centrally to the top of the sides of the upper rubber is the strip 1, and projecting-upwardly from the center of this strip is the standard J, having a pintlej at its upper end. This pintle rests in the elongated slot in the rocking arm G, and as the arm G is rocked it follows that the upper rubber H, which, as before stated, is connected thereto by the standard J, is rocked in the opposite direction.

As the upper rubber is raised by the introduction of additional clothes between the rubbers the point ofconnection between the slotted rocking arm G and standard J is changed or moved away from the pivotal point of the slotted rocking arm, thus increasing the throw or swing of the upper rubber.

With this construction it will be seen that by throwing up the cover B the upper rubber H is raised out of the tub sufficiently for the introduction of the clothes to be washed, and by disconnecting the two sections of pitman D the lower rubber is free to be removed.

I In the construction shown in Fig. 6 I have simply transferred the rocking arm G to the under side of the cover or lid, and instead of connecting the slotted arm to the upper rubber by means of a long standard secured on a crossbar carried by the upper rubber I provide a short standard J and connect it to the ends of the rubber by the brace-rods h, the short standard carryinga pintle which rests in the slot in the rocking arm G. In this modification, as in the main device, the upper rubber is mounted centrally at its sides on pintles resting in oblong bearings 6, carried by the cover or lid.

It is evident that many slight changes might be resorted to in the relative arrangement of parts herein shown and described without departing from the spirit and scope of my invention. Hence I would have it understood that I do not wish to limit myself to the exact construction herein shown and described; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a washing-machine the combination with a tub, a lower rubber pivotally mounted in the tub, a top or cover hinged to the tub, and an upper rubber pivotally mounted in elongated hearings in the top or cover, of a crank-shaft carried by the top or cover, a pitman pivotally connecting the crank and lower rubber, a slotted rocking arm carried by the cover, a pitman connecting said arm and crank and a standard carried by the upper rubber and having a pintle resting in the slot in the rocking arm, substantially as set forth.

2. In a washing-machine, the combination with a tub, a lower rubber pivotally mounted in the tub, a top or cover hinged to the tub, and an upper rubber pivotally mounted in elongated hearings in the top or cover, of a crank-shaft carried by the cover, a pitman pivotally connecting the crank and lower rubber, a rocking arm mounted 011 and projecting upwardly above the cover, a pitman conmeeting said arm and crank and a standard carried by the upper rubber and passing through the top and having a sliding connection with said rocking arm.

3. In a washing-machine, the combination with a tub, a lower rubber pivotally mounted in the tub, a top or cover hinged to the tub, and an upper rubber mounted in elongated bearings in said top or cover, of a two-part pitman, one part connected to the lower rubber and the other part mounted on the crank, means for detachably connecting the adjacent ends of the pitman and means for rocking the upper rubber.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

JOHN R. CARTER.
